Starch is natural biopolymers with diversified applications as a biodegradable material which is a suitable alternative of non‐biodegradable and non‐renewable materials. The use of nanofiller as reinforcement results in considerable improvement in various properties of starch. Herein, nano calcium carbonate (CaCO3) designed starch bionanocomposites are prepared by solution technique. Fourier transform infrared spectroscopy and X‐ray diffraction are used for study of structural interaction of nano calcium carbonate with starch. The morphology of starch/CaCO3 bionanocomposites is investigated by high resolution transmission electron microscope. The thermal stability of starch is increased substantially due to incorporation of stable calcium carbonate nano powder. It is found that the 40% of residual mass was left at 800°C with a loading of 8 wt% of CaCO3. The oxygen permeability of starch/CaCO3 bionanocomposites is decreased by three times as compared to the virgin starch. Their biodegradability and chemical resistance properties are investigated. The tensile strength of starch/CaCO3 bionanocomposites is also improved with incorporation of nano CaCO3. The prepared bionanocomposites with substantial reduction in oxygen barrier properties in combination with increased thermal stability, tensile strength, and chemical resistance properties can be suitable materials for packaging applications.

“…Figure 7 shows the SEM micrographs for tensile specimens with maximum and minimum values of tensile strength after failure. Figure 7a shows the completely broken fibre during failure which demonstrates the existence of good interfacial [15]. Figure 7b shows that composite specimen (A = 5.26, B = 4, C = 98) has voids near interface regions and also exhibits fibre pull out owing to poor interfacial adhesion.…”

“…A study on investigation of the effect of red mud [15] on the mechanical properties of banana-polyester composites revealed that addition of red mud greatly enhances the mechanical and damping properties of BFRP (banana fibrereinforced polymer) composites. Red mud, when added to glass-epoxy and bamboo-epoxy, results in increase in mechanical properties as well as wear resistance of hybrid composites [16].…”

At present, hybrid natural fibre-reinforced polymer composites are popularly used for their remarkable specific strength. Natural fibre polymer composites have been explored by the researchers for their sprawling use in engineering applications. To achieve better mechanical properties, it is needed to test hybrid natural fibre composites with all possible combinations of their compositions which require a lot of resources. Thus, the present work deals with the investigation of mechanical properties of hybrid abaca-epoxy composites. Experiments were carried out according to full factorial design with three input parameters namely weight per cent of abaca fibre, particle size of red mud and weight per cent of red mud. Subsequent to this, a fuzzy model is developed to predict the mechanical properties such as tensile, flexural and impact strength of hybrid abaca-epoxy composites based on the experimental results obtained by their mechanical characterisation. Membership functions were constructed such that the fuzzy model can precisely predict the mechanical properties of hybrid composites. Moreover, a set of test case experiments were conducted so as to validate the fuzzy model. It was inferred from these test case results that the developed model can be used to predict mechanical properties of hybrid composites with a maximum accuracy of 87%.

Composites are primarily made using matrix and reinforcement as major components but may also contain several other fillers or additives. A majority of the composites are made using synthetic fibers and polymers. However, in the last few decades, focus has been on developing biocomposites using renewable resources. Conventionally, biocomposites are developed using natural fibers such as jute, Kenaf, or Ramie as reinforcement and synthetic resins such as polyethylene, polypropylene and epoxy as matrix. Typically, biocomposites contain either the reinforcement or matrix which makes the composites partially degradable. Such partially degradable composites provide good properties, but the presence of a nonbiodegradable component, particularly as a matrix limits their biodegradability. Alternatively, composites that contain both the matrix and reinforcement from renewable resources which make the composites completely degradable have also been developed. However, these completely biodegradablebiocomposites do not have the desired mechanical properties and stability at high humidities or in aqueous environments which restricts their application. In addition, natural fibers and resins used in biocomposites have inherent limitations and also not easily processable. To overcome limitation of using a single reinforcement or matrix derived from bioresources, hybrid composites that contain more than one reinforcement or matrix are developed. Such hybrid composites are manufactured by either intimately mixing two or more fibers or other reinforcing materials or by placing different layers of the reinforcement and molding them into composites using one or more resins. Conventionally, hybrid composites refer to metallic and ceramic based reinforcement, matrix and fillers. Although hybrid biocomposites are gaining significant attention, the presence of multiple reinforcements and/or matrix makes it difficult to process and also to predict the properties of such composites. Hence, understanding the properties and potential of using multiple reinforcements and/or matrix materials from renewable resources to develop biobased hybrid composites is highly desirable. This article discusses hybrid composites that contain a major proportion of renewable materials. Hybrid composites not only provide better properties but could also lead to substantial cost reduction due to the incorporation of inexpensive raw materials. These composites show potential for use in aeronautical, sporting goods, wind power turbine blades, helmets and civil construction such as pedestrian bridges and many other applications. This review provides an overview of the biobased materials used to develop hybrid composites, their processability and their potential applications. POLYM.
